To zz wim e may mmf Be it known that I, MARGARm E. Hos- 'rATnR, a citizen of the United States, resid- 1 ing at Buffalo, in the'county of Erie and State 'of New York, have invented'certain new and useful Improvements in Dishwashing Machines, of which the following lis a specification.

This invention relates to dish 'washingmachines and particularly to that type wherein the dishes aredisposed in a perforate receptacle rotatably mounted in a container partially filled with cleansing Aiuid such as' hot water and soap.

. Another object of the invention is 4'-to improve upon the dish washing machines now 1n use by reducing the number of parts necessary to accomplish the result ,and by y so constructing those parts remaining that accumulation of sediment will be prevented and. cleaning of the machine will be greatly facilitated.

Other objects will be in part obvious and in part pointed out hereinafter. v

The invention consists, furthermore, in

the novelv arrangement and combination of parts hereinafter described, as well as in the details of the construction of the same, all of which will be more fully described in the following specification, and then finally embodied in the claims which are appended to thisspecification ,and whichI form an essential -part thereof.

In the drawings Figure 1 is a sectional side elevation of the operative assembly. v

Figure 2 is a plan view of the base partly in section, with the `operating mechanism removed. 3 d. l p t,

igure 1s a etai view o a.v po ion ofthe 'stalling box.

Figure 4 is an inverted 111plan view of the erforated-greceptacleY ustrating' the rein orcing bars for the bottom of the receptacle.

Like characters of reference refer to like or` corresponding parts throughout both views, in the dra-mugs.

. in a containerA mounted on a base having rotatabl mounted therein a perforate receptacle actuated by a driving ele'- ment D connected with a suitable source of power (not'shown) such as an electric' motor or provided with a crank handle (not .and

shown) for manual o eration as is the case A, s

with the embodiment and described in detail. v y

The container A is formed' of a, body portion 1, the lower edge of Swhich is bent' inwardly substantially at right angles there'- to to form an annular iiange 2 to. which the bottom 3 is secured by means of bolts 4 extending through the base B,and' serv ing also to hold the container thereupon', Formed concentrically of thel bottoinls opening 5 th edges'cf which are secured to the .base B as at 6, for receivlnggthe;

reinafter illustrated drive shaft of a drive el enen1';f1 (hereinaftdescribed) suitable packing being. provided to prevent leakage from the container there about. Another opening7 comm'unicatllgwith a conduit (not shown). -seryes as a drain for carrying off the cleansmg fluld subse uent to use of the machine.' 4 Theupper edge of the side wall v1 is beaded as at 8 for sup orting a cover 9 havmgsecured on the under portion of its perlpheral edge In general termsthe invention consists an annular L-shaped ring 10 for engagingA about the bead as is illustrated. Riveted as at 11 toI the nether face of thecover 9 and in line with ,the opening 5 is a stub bearing 12 the ur ose of which willl be hereinafter describe Suitable handles 13 Vare provided for facilitating removal of the cover.

The base B is provided with a plate top portion 14 secured to( the container as at 4 and is preferably cut away as at -15 1n the quadrants to decreasethe welghtV thereof, the peripheral edges thereof being Iianged as at 16 and 17 for receiving the container A and for receiving the sup orting legs 18 respectively; the upper en s of sald legs 18 bemg bent as at 19 to engage the inner surface and lie flush with the outer surf-ace as is shown in Figure l. Bolts 20" are provided for securing the legs to the flange 17and the lowerends of the legs are`likewise bent asat 21'fcr attachment by bolts 22 to the flange 23 formed on the bottom portion 24. ofthe base. Furthermore the 'bottom portion isprovided with foot flanges 25 and is cut away 1n quadtive movement thereof.

rants as at 26 .to lighten the frame. Suitable securing means (not shown) may be inserted through openings 27 in the flanges for mounting the machine upon a stand. Aligned openings 28 and 29 formed concentrically in the top and bottom :portions of.

. ing in the latter registering with the opening 14'. The bottom 3 of the container is provided with a centrally disposed opening 5, and across said opening extends the disk 16. Hold fast devices 6 are employed for connecting the bottom 3 to the plate .14, as well as connecting the disk 16 therewith. Extending through the opening 14', as well as into the aperture of the disk 16, and i'urtliermore depending fromthe plate 14, isla bearing sleeve 17', formed with an annular flange 18', and Ifurther having its lower p ortion peripherally threaded. The bearing sleeve 17', is secured with the plate 14, through the medium of the hold fast devices 6, engaging the ange 18. Interposed between the flange 18 and the plate 14, is an apertured disk Y.

The disk 16 is formed of asbestos, and the disk Y made of rubber. The disks are employed to prevent leakage of the cleansing fluid. Threadably engaging with the bear.

ing sleeve 17', is alock nut 62, carrying a packing 19'. A. spring 62' is employed and which engages in the nut 62, to arrest rota- The nut 62 is formed with peripheral grooves 63, for the receptionl of the zpring 62', the latter is sen cured to and depends from the plate 14.

A receptacle C for containing the plates or dishes to be l1washed is provided with a side wall 33 and a bottom 34 perforated as at 35 and said bottom bein ianged as at 36 for securement to the side wall 33'by bolts or rivets 37 carried by transverse rein- .forcing bars 38, the, medial portion of which is depressed as at 39 and-provided with a squared opening 40 for receiving the drive shaft of the drive element D. As the receptacle is revolved through connection o the drive element D, with the medial portion of the transverse bars 38 they are secured throghout their length to the bottom by spac rivets 41. Adjacent the upper edgeof .the side wall 33 is an overflow opening 42 reinforced by a plate or casting opposite 43 suitably secured as at 44 thereabout. rlhe `upper edge of the wall 33 is beaded as at 45 for'supporting a cover 46 to which is secured on its under side adjacent the peripheral edge thereof an annular L-shaped'ring 47 for'engaging about the bead as is illustrated. Handles 48 are mounted in the bent portion ofthe wall forming the bead 45. The handles 48 are extended upwardly through recesses formed in the ring 47 and cover 46 to prevent independent rotation of the cover with respect to the body of the receptacle, and said handles 48 also provide means for lifting the receptacle C audits cover 46 together'. Mounted concentric of the cover and in alignment with the stub bearing 12 and squared opening 4() is a pintle 49 journaled in the stub bearing 12 for an obvious purpose. Suitable handles 50 are provided for removing the cover independently of the body portion of the receptacle C.

The drive element D includes a transverse crank shaft 51 mounted in the eXtension 3 and opening 32 in one of the legs 18 ofy the base B and has thrust collars 52 secured thereon for preventing lon 'tudinal movement thereof. A. vertical drive shaft 53 has its lower end anti-frictionally mount- `ed in the stub bearingI 54 provided with a ball-race 55 for receiving the ball bearings 56 and is provided with a bevel gear 59 intergeared with a master gear 60 on the crank shaft for rotating the drive shaft. A suitable closure plate 57 is bolted therebeneath for an obvious purpose. The end of the drive shaft is squared as at 61 for reception within the squared opening 40 in the transverse bars 34 of the bottom of the receptacle C; the under portion of the bars adjacent the squared opening abutting the upper portion of the sleeve 58 for supporting the receptacle in spaced relationship to the container A.

The terminal of the crank shaft 51 is squared as at 64 for receiving either a crank handle (not shown) or for connection with a suitable power plant such as a motor (not shown).

In operation the container A is partially filled with a cleansing fluid such as soap and Water and the dishes are placed in the receptacle C, whereupon theicrank shaft 51 of the drive element D is rotated consequently rotating the receptacle C through the drive shaft 53 causing the cleansing fiuid (on account ofits inertia) to pass rapidly over and between the dishes removing the particles of food or other matter. The container is then drained through the opening 7 and clean hot water placed therein and the operation repeated.

Many changes may be made in the construction of the device as a whole, and in the several parts as well as in their combina-v Y said bearing, and a tions and many rearrangements of the several parts may be had without in any wa departing from the field and scope o the present invention as disclosed by this application, wherein only the preferred form of the salme has been shown and described.

What I claim and desire to secure by Letters Patent is: p

1. In a washing machine a rotatable foraminous receptacle having driven means connected with its bottom for rotating it, a bearing arranged above said receptacle, a removable cover for said receptacle rovided with a bearing element extending into ifting means carried by the body of the receptacle and extending through the cover to provide for the bodily rotation of the latter with said body portion.

2. In a Washing machine a rotatable foraminous receptacle havin driven means connected with its bottom or rotating it, a bearing arranged above said receptac e, a removable -cover for Ysaid receptacle provided centrally with a bearing element extending into said bearing, lifting means carried by the body -portion of the receptacle and extending through the cover to provide for the bodily .rotation of the latter with said body portion, and means for lifting the cover independently of the lifting means for the body of the receptacle.

In testimony whereof, I ax my signature hereto. l

MARGARET E. HOSTATER.
